HAND-LEVER FOR STEAM-PUMPS.

JZEPECIPICATION forming part of Letters Patent No. 301,3i9, dated July1, 188%.

Application filed February 18, 1884. (No model.)

To all whom it may concern:

Be it known that I, Gnonen E. ELLIOTT, a citizen of the United States ofAmerica, resid ing at Calais, in the county of Washington and State ofMaine, have invented a new and useful Hand- Lever for Steam-Pumps, ofwhich the following is a specification.

My invention relates to improvements in detachable hand-levers forproducing reciprocating motion, and is particularly adapted as anattachment in connection with steampumps for operating the pistons byhandpower when the supply of steam is insuffibeen used for the purposesnamed a lever forked or slotted at its lower end to pass over two pins,one of which is attached to the tappet-arm and the other to a bracketprojecting down from the yoke or base of the pump and forming a fulcrumfor said lever. A lever pivoted to a frame upon the pumps yoke or base,and provided at its lower portion with an eye having a slotted extensionin order to admit of its connection with a bolt or headed projectionupon the piston-rod, has also been employed, as well as various othersmore or less complicated in construction and unsatisfactory inarrangement.

The object of this arrangement is to provide a hand-lever for thepurpose named that will be simple and effective in its construction andoperation, readily attached to or detached from a steam-pump, asoccasion may require, and which will be more easy and even in itsoperation than those now in general use- My invention therefore consistsin the novel construction and arrangement of the parts, as will behereinafter described with reference to the accompanying drawings,wherein Figure l is a view in side elevation of a steam-pump, the yokebeing broken away to show the application of my improvements. Fig. 2 isa detail view of the hand-lever, and Fig. 3 is a view in detail of thebracket, lug, and nut.

The letters A B represent the cylinders of a steam-pump, connectedtogether by a yoke or base, 0, and provided with the usual pistons, I),and piston-rod E, the latter having secured thereto the tappet-arm F,the upper end of I which is fixed to the valve-rod in the usual manner.

Projecting down from and forming a part of the base of the yoke C is abracket, G, the yoke or base being slotted at the point of junction withthe bracket, as shown at a. Connected to this bracket Gisalug, H, formedwith an eye, a, and provided with a screwthreaded extension, I), andadapted to pass through a perforation in said bracket and be held inplace by a nut, the lug being fitted loosely in the perforation in thebracket, in order that it may have free play and turn with the movementsof the lever when being operated. In this eye a is inserted the lowerend of the lever I, the end of which is tapered and shouldered, asshown, and fits loosely in the eye of the lug, loosely secured to thebracket on the yoke, the said lever having that portion extending fromthe lowerend to the point of contact with the lug or pin on thetappet-arm curved, substantially as shown in the drawings at d, and alsoformed with the downward-extending side lip or hook, c, the base ofwhich serves as a seat when the lever is put in operative connection, inwhich connection the hook fits over and rests on the stud f on thetappet-arin F.

The adjustment of my hand-lever in operative connection is apparent. Thelever-point is inserted through the slot in the yoke into the eye in thelug secured in the depending bracket, and the hook or lip placed overthe lug or pin on the tappet-arm, when the lever drops-of its own weightinto position, and is ready for use.

It will be observed that this lever can be readily attached and aseasily detached, the length of the hook and the length of the part whichfits into the eye of the lug on the bracket corresponding, in order thatwhen one connection is released the other is also, and the implement canbe lifted from its place freely. The function of adaptability to themovements of the lever given to the lug in the 9 bracket obviates allstrain that would exist in that connection were the connections rigidlyfixed.

What I claim as my invention, and desire to secure by Letters Patent,is-- 1. The hand-lever I, formed with the side the tappet-arm, allconstructed and combined lip or hook, e, and having its lower endtapered to operate substantially as and for the purand shouldered,substantially as described, pose set forth. and for the purpose setforth. In witness whereof I have hereunto set my I 5 2. The hand-1everI, formed with the side hand in the presence of two attesting witlip orhook, e, and having its lower end tapered nesses.

and shouldered the yoke or base provided w with a slot and a dependingbracket, having EDMUND ELLIOTT loosely secured therein a lug formed withan Attest:

eye adapted to receive the lower end of the G120. H. BOARDMAN,hand-lever, and a stud or pin projecting from N. Q. BOARDMAN.
